HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 235, 121 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 235, 121 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 235, 121 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 235, 121 is 1.
HCF(235, 121) = 1
HCF of 235, 121 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 235, 121 is 1.
Highest Common Factor of 235,121 is 1
Step 1: Since 235 > 121, we apply the division lemma to 235 and 121, to get
235 = 121 x 1 + 114
Step 2: Since the reminder 121 ≠ 0, we apply division lemma to 114 and 121, to get
121 = 114 x 1 + 7
Step 3: We consider the new divisor 114 and the new remainder 7, and apply the division lemma to get
114 = 7 x 16 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 235 and 121 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(114,7) = HCF(121,114) = HCF(235,121) .
